It has been discovered that the current procedure doesn't work for all possible values that might go to ZQ0SR0 due to hardware bug. The workaround to this is to avoid storing some values in ZQ0SR0. Thus Linux will read the ZQ0SR0 register and cache its value in RAM after processing it (using modified_gray_code array). The bootloader will restore the processed value.
